6 plates and 5 cups cost 23.80 dollars. 7 plates and 6 cups cost 28.00. Each plate costs the same as the other plates, each cup
andrey2020 [161]
Cups = c
Plates = p

6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00


Now use algebra to have the 30c be on one side and the rest on the other:

36p + 30c = 142.80 | -36p

30c = 142.80 - 36p


35p + 30c = 140.00 | -35p

30c = 140.00 - 35p


Now set them equal to each other about the 30c:

142.80 - 36p = 140.00 - 35p


Use algebra to solve for p:

142.80 - 36p = 140.00 - 35p | +36p

142.80 = 140.00 + p | - 140

2.80 = p


Go back to one of the "30c" equations and plug in the value for p:

30c = 140 - 35p

30c = 140 - 35(2.80)

30c = 140 - 98

30c = 42 | /30

c = 42/30

c = 1.4


Plates are $2.80
Cups are $1.40

Theresa owes $9,000 on her car loan. If the value of her car is $15,000, what is her equity in the car?
Schach [20]
Hi there

Since Theresa owes $9,000 this amount enters in liability

the value of her car which is 15000
This amount enters in assets

So to find the equity in the car
Owners equity=assets-liability
Owners equity=15000-9000=6000

6000 is the equity in the car

Good luck!
